Application May 13, 1952, Serial No. 287,575

1 Claim. (Cl. 29275) I have invented an improvement in securing devices, particularly a catch for holding a door or other member closed, but permitting it to be opened at W111.

The device, in the best form now known to me, contains a yielding member or bolt-latch which is enclosed in a suitable casing, so that it can readily be fastened in place. This member includes a carrier slidably mounted in the casing and engaged at its opposite sides therein, so as to have a short range of inward and outward movement. The carrier is forced by a spring to pro ect from the casing, but it will give when the door or the like is to be released. The carrier has a rotatable element on its outer end to seat against a strike plate and keep the door shut.

An important object of this invention is to provide a securing device of this type, that is simple 1n design, can be easily, inexpensively and quickly made and assembled, and will be efficient and durable in operation and use.

The nature and advantages of the invention are clearly explained in the following specification and the drawings illustrate the preferred construction and arrangement of parts, but changes may be made in minor structural details without deviating from the general combinations that are defined in the appended claim.

On the drawings:

Figure 1 is a perspective view of the casing to receive the holding member.

Figure 2 is a perspective view of the holding member carrier.

Figure 3 is vertical longitudinal section of the assembled device on line 3-3 of Figure 4.

Figure 4 is horizontal longitudinal section on line 4-4 of Figure 3.

Figure 5 is a vertical cross section on line 55 of Figure 3; and

Figure 6 is a vertical cross section on line 66 of Figure 3.

A easing, open at the front and bottom, has a top 1 with sides 2 and a back 3. The sides are bent outward along the bottom to present extensions 4 with apertures, such as slots 5, to receive screws to attach it to a support. The front edges of the sides have projections 6 to be bent inward and across the open front.

inside the casing is the yielding member that forms the principal part of this improvement. This member comprises a U-shaped carrier 7 having sides 8 inclined upward and bottom 9, with projections 10 at the front ends of the sides. A transverse pin 11 fixed at its ends in the projections 10 mounts a rubber roller 12 between the projections 10. In the sides 8 of the carrier are longitudinal slots 13 and the projections 6 at the front of the casing are bent into these slots 13. A projection or lug 14 extends up from the rear or inner edge of the bottom and has a punch protuberance 15 to seat one end of a spring 16, which abuts the closed back 3 of the casing and pushes the carrier through the open front of the casing till projections 6 engage the rear ends of the slots 13, but the yielding member can slide inward nearly as far as the projections 6 permit. The rubber of which the roller 12 is made is not entirely hard, but somewhat compressible.

A strike-plate is indicated at 17 to cooperate with the unit above described. This plate has screw-holes 18 in its ends and a longitudinal projection 19 in the middle near its front edge. At the opposite edge is a central stop 20.

The plate 17 is attached, for example, to a fixed part, which may be the inner face of a door frame or of a side of a cabinet or chest at a point adjacent the edge of a door when the latter is shut. On the inner face of the door the casing and yielding member therein are made fast in line with the plate 17. When the door is closed the roller 12 is forced by the projection 19 to thrust the channel-shaped carrier 7 inward of the casing, thus compressing the spring 15. As soon as the roller passes the projection 19 it is arrested by the stop 20, and seats in the space between the projection 19 and stop 20. The carrier, roller 12 and spring 15 thus constitute yielding latch means in the casing. When desired, the door can be opened by a pull strong enough to move the roller past the projection 19. The stop can be omitted if the strike plate 17 is affixed adjacent a shoulder in a cabinet or door frame, on which the plate 17 will be mounted in use. i

The back 3 of the casing may have it lower edge bent inward to form a transverse ledge 21. This ledge with the top sides and back forms a pocket that prevents the spring from dropping out of the casing before the device is mounted for use.

The catch thus serves fully all the purposes for which the improvement is intended. It can be produced and assembled at low cost and is smooth and noiseless in operation.

Having described my invention, what I believe to be new is:

A securing device comprising a casing having a closed top, back and sides, with open bottom and front, the, back having a bent edge presenting a transverse ledge across said bottom to form with the top, back and sides a pocket at the rear of. the casing, a carrier in the casing, the carrier being open at the top and having sides and a bottom connecting said sides at the bottom of the casing, the sides of the carrier being inclined upward to form projections at the top of the carrier, the sides having longitudinal slots adjacent their front ends, below said projections, the casing having inturned opposed projections, one at each side in its front, engaging said slots, a rotatable element mounted at the front: end of the carrier between said projections, the bottom of the carrier having an upturned lug at its rear end, and a spring seated at one end on said lug with its opposite end in said pocket and abutting the back of the casing.
